UniProt functional annotation for Q0PB48 | ||
|
|
|
|
|
|
||
| UniProt code: Q0PB48. |
|
||
| Organism: | |
Campylobacter jejuni subsp. jejuni serotype O:2 (strain ATCC 700819 / NCTC 11168). |
| Taxonomy: | |
Bacteria; Proteobacteria; Epsilonproteobacteria; Campylobacterales; Campylobacteraceae; Campylobacter. |
|
||
|
||
| Function: | |
Has been suggested to be involved in cytochrome c peroxidase or P450-like oxygen chemistry or cyanide detoxification. The high oxygen affinity of this protein suggests that it probably does not function as an oxygen transporter. |
|
||
| Cofactor: | |
Name=heme; Xref=ChEBI:CHEBI:30413; Note=Binds 1 heme group per subunit; upon expression in E.coli it purifies predominantly in the Fe(2+)-oxy form, binding O(2) tightly even under anaerobic conditions.; |
| Subunit: | |
Monomer. {ECO:0000269|PubMed:16681372, ECO:0000269|PubMed:17023416}. |
| Subcellular location: | |
Cytoplasm {ECO:0000305|PubMed:16339953}. |
| Induction: | |
Constitutively expressed, it is further induced by S- nitrosoglutathione (GSNO) and S-nitroso-N-acetylpenicillamine (SNAP) (at protein level). {ECO:0000269|PubMed:16339953}. |
| Disruption phenotype: | |
Cells lacking this gene grow less well than wild- type under conditions of high aeration. {ECO:0000269|PubMed:16339953}. |
| Similarity: | |
Belongs to the truncated hemoglobin family. Group III subfamily. {ECO:0000305}. |
